OPTIMALISASI PENGONTROLAN PENGISIAN BATERAI HIBRID PLTS-PLN PADA WAKTU BEBAN PUNCAK

Abstract

The daily load curve of PT. PLN shows the tendency of a large difference between the peak load time load(WBP) and the outer peak load time (LWBP). So that the plants that are ready to operate are needed to service changes inload from LWBP conditions to WBP. To reduce electricity consumption by customers of PT. PLN in WBP requires asubstitute electrical energy source. This study designs and implements the use of Solar Power Plants (PLTS) to replacethe source of PT. PLN on WBP. The PLN source will supply the load at the time of the Peak Load Time (LWBP), whichis 22.00-17.00 WITA, while the PLTS source is designed to supply the Peak Load Time Load (WBP) at 17.00-22.00WITA. Transfer from PLN to PLTS or vice versa is automatically controlled. PLTS during the day will store electricalenergy into batteries that are controlled with the Solar Charge Controller (CCR). The choice of SCC is important becausethis section controls the charging of the battery from the power source produced by the solar panel. Optimization of SCCcontrol can be done by choosing SCC that has better filling characteristics. This study tested 3 PWM type SCCs to seethe filling characteristics and the results of SCC with S Series brands are the best compared to OEM brands and Y-Solarbrands.
